Note:

1. 47uF capacitor must be close to DACOVDD33A and DACOVSS33A.

2. If any of OSCXI, OSXO, and ECLK is not used, it needs to connect to GND.

3. The cascade resistor and parallel capacitor on CMD, RD, WR, and CS pins can reduce noise interference. In general,

resistor is short and capacitor is open. Please preserve the options on PCB.

4. R2 resistor can adjust headphone volume.
